Storage device and recording medium formatting method using a phase shift between data sectors in adjacent cylinders

摘要

A predetermined number of sectors are formed on respective predetermined cylinders of a predetermined recording medium of a magnetic disk. and a magnetic head moves to and is positioned at an objective sector of an objective cylinder so that information recording and/or reproducing is performed on the objective sector of the magnetic disk through the magnetic head. Positions of all the sectors formed on the predetermined cylinders are such that a phase difference within a sector length is provided at least between adjacent cylinders.
